Signal generation device and a mobile communication terminal test equipment and signal generation method and mobile communication terminal test method with it

摘要

To provide a mobile communication terminal test device that can generate a signal with amplitude-frequency characteristics or phase-frequency characteristics which are changed over time. A mobile communication terminal test device 10 includes a data generation unit 12 that generates a bit stream, a sub-carrier generation unit 31 that receives bit stream data and performs, for example, predetermined encoding, symbol mapping, or sub-carrier mapping to convert the received data into a plurality of sub-carriers based on an OFDM modulation system, a frequency characteristic storage unit 13 that stores table data for predetermined amplitude-frequency characteristics and phase-frequency characteristics, and a frequency characteristic calculation unit 32 that sets the amplitude and phase of each sub-carrier input from the sub-carrier generation unit 31 on the basis of the table data.
